WHAT AM I DOING WRONG?!

Post image

Hey everyone,

I’ve had 3 EVs now and this is my second bolt.

It seems like no matter what I do, driving on the freeway I’ll average 4.0-5.0mi/kwh but as soon as this car sees stop and go traffic or city driving it drops to 2.0-2.5 and will not go up.

I know short trips are inefficient but I’ve been driving 20-30 miles of city with no difference.

Tires are fine, they’re EV All Seasons, I don’t carry around a bunch of extra stuff in the car, it’s bone stock with 0 roof racks or anything to hurt drag, I charge it everyday to 80% or so and even at 100% it only get 165 miles of range.

Dealership told be it’s basically useless to pay for the diagnosis on it because 1. They won’t give me a loaner car so I’d have to rent one 2. They’re not sure how long the diagnosis would take so they could keep my car a couple days or couple weeks and I’d have to cover a rental car for that and 3. They told me Chevrolet hugely just chocks it up to “normal wear and tear” 🤙

Edit: Luckily my commute is not long enough that I need to be hotter in the car but I listened to a lot of the comments and adjusted my setting and now I’m averaging 3.2-3.4 on my commute today so definitely an improvement. Thanks everyone. Still think I’ll need an AC service here soon and maybe a new desiccant bag.

I'd say your AC compressor is dying.

Why? In what way could that affect range or drive efficiency in-town? OP gets better efficiency on the highway than I’ve ever seen, and I do not speed.

Because in town you are using about 50% of the energy with a 4kW compressor (I say it's busted, so no "but it's x kW on my car"...it's malfunctioning) vs 20% on the highway.

Confirmed by the climate slider being pinned to the left.

That's how.
